Calibrachoa plant named ‘Wescaice’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Wescaice’, characterized by its cascading, roughly spherical plant habit; plant branches with tightly spaced internodes; large ovate-shaped leaves; freely flowering habit; uniform flower size; and flowers that are light blue in color.

Botanical classification/cultivar designation: Calibrachoa sp. cultivar Wescaice.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp., and hereinafter referred to by the name ‘Wescaice’.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the program is to create new Calibrachoa cultivars with compact and cascading growth habit, freely branching habit and attractive flower colors.

The new Calibrachoa originated from a cross-pollination made by the Inventor during 2000 of a proprietary selection of Calibrachoa identified as code number 00P108, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa identified as code number 00P150, not patented, as the male, or pollen, parent. The new Calibrachoa was selected by the Inventor in 2000 in a controlled environment in Südlohn, Germany from within the progeny resulting from the cross-pollination.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Südlohn, Germany since 2000, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Wescaice have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Wescaice’. These characteristics in combination distinguish ‘Wescaice’ as a new and distinct cultivar of Calibrachoa:

1. Cascading, roughly spherical plant habit.

2. Branches with tightly spaced internodes.

3. Large ovate-shaped leaves.

4. Freely flowering habit.

5. Uniform flower size.

6. Flowers that are light blue in color.

Plants of the new Calibrachoa produce flowers that are more open in shape and different in color than plants of the female parent. Also, plants of the new Calibrachoa have flowers that remain open under low light levels. Plants of the new Calibrachoa have flowers that are a different color than plants of the male parent. Plants of the new Calibrachoa also have thicker branches and larger leaves than plants of the male parent.

Plants of the cultivar Wescaice can be compared to plants of the Calibrachoa cultivar Wesviolet, disclosed in U.S. Plant Pat. No. 12,584. However in side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa and the cultivar Wesviolet, differed in the following characteristics:

1. Plants of the new Calibrachoa had larger and more rounded leaves than plants of the cultivar Wesviolet.

2. Plants of the new Calibrachoa had wider sepals and longer peduncles than plants of the cultivar Wesviolet.

3. Plants of the new Calibrachoa produced larger flowers than plants of the cultivar Wesviolet.

4. Plants of the new Calibrachoa and the cultivar Wesviolet differed in flower color.

Plants of the cultivar Wescaice can also be compared to plants of the Calibrachoa cultivar Carillon Blue, not patented. However in side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa and the cultivar Carillon Blue, differed in the following characteristics:

1. Plants of the new Calibrachoa had more rounded leaves than plants of the cultivar Carillon Blue.

2. Plants of the new Calibrachoa had shorter internodes than plants of the cultivar Carillon Blue.

3. Plants of the new Calibrachoa produced larger flowers than plants of the cultivar Carillon Blue.

4. Plants of the new Calibrachoa and the cultivar Carillon Blue differed in flower color.

5. Plants of the new Calibrachoa had broader sepals than plants of the cultivar Carillon Blue.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the aforementioned photographs and following description were grown under conditions that closely approximate commercial production conditions during the spring and summer in Südlohn, Germany in a glass-covered greenhouse. Plants were about 20 weeks old from planting rooted cuttings. During the production period, day temperatures ranged from 20 to 25° C., night temperatures ranged from 16 to 18° C. and light levels ranged from 3,000 to 50,000 lux. Plants grown in 12-cm containers were used for the following description.
